WIDEBAND X-BAND MICROSTRIP BUTLER MATRIX [PDF]
Progress In Electromagnetics Research, 2007 This paper presents the design of a wideband X-band microstrip 4×4Butler matrix. The wideband performance of the Butler matrix means that it possesses equal coupling and difference of phases throughout the operating band. Design of the wideband components such as 3-branch branch line hybrid, crossover and Schiffman line phase shifter are presented in ...
